| Abstract |
Vehicle-to-Everything (V2X) communication, particularly Cellular V2X (C-V2X), is gaining attention in the development of autonomous vehicles and smart transportation systems due to its ability to share real-time traffic information over long distances. While current research and applications focus on the periodic low-speed data message transmission, such as Cooperative Awareness Messages (CAM) and Basic Safety Messages (BSM), utilizing C-V2X, high-speed data message sharing, such as sensor data, is essential for providing services like remote driving. Therefore, in this study, we assumed a communication scenario for sharing real-time camera sensor footage between vehicles and base stations using MATLAB-based simulations and analyzed the video transmission performance in 4G LTE and 5G NR environments. To evaluate the video transmission performance, we analyzed the latency and available frames per second (FPS) according to the modulation and coding scheme (MCS), compression, and image resolution. |
